DHCP Best practices including 80/20 rule
Posted on 2008-01-25
Our current DHCP environment is in need of overhaul. We have 60 scopes currently, running on one clustered server. This has been in place for several years, and is also a file server.
We intend to relocate this onto dedicated redundant servers. I've been reading several MS documents where they recommend setting up 2 servers with the same scope, set up with one server to issue 80% of the addresses and the other to issue 20%. Doesn't the 20% just run out and stop giving out addresses?
What do others here do? We have approximately 350 servers and 3000 desktops, along with several hundred other IP devices.
We will also be overhauling DNS and WINS, so if that matters I'd love to hear the suggestions. We use Active Directory integrated DNS with a single forest/domain.
